Abstract A high accuracy stable Dispersive Boundary Condition(DBC) is presented, which can be used to model wave propagation in transmission lines by the finite-difference time-domain method. The differential factor in the boundary condition is replaced by a new two-order difference scheme. The new DBC has the same absolute stability as that proposed by P. Y. Zhao, et al. (1994), but it has a much better absorbing performance.
